“…A number of subsequent studies have demonstrated robust adaptation aftereffects for faces, with manipulations of face shape using different forms of distortion (Rhodes et al, 2003; Carbon and Leder, 2005; Carbon et al, 2007; Jeffery et al, 2007; Carbon and Ditye, 2011; Laurence and Hole, 2011) or through the creation of anti-faces which manipulate aspects of facial shape that are crucial to identification (Leopold et al, 2001; Anderson and Wilson, 2005; Fang et al, 2007). These studies suggest that faces are coded with respect to a prototypical or “average face” and show that sensitivity changes with adaptation, so that perceptual judgments are made with respect to a shifted norm.…”

Evidence that self-face recognition is dissociable from general face recognition has important implications both for models of social cognition and for our understanding of face recognition. In two studies, we examine how adaptation affects the perception of personally familiar faces, and we use a visual adaptation paradigm to investigate whether the neural mechanisms underlying the recognition of one’s own and other faces are shared or separate. In Study 1 we show that the representation of personally familiar faces is rapidly updated by visual experience with unfamiliar faces, so that the perception of one’s own face and a friend’s face is altered by a brief period of adaptation to distorted unfamiliar faces. In Study 2, participants adapted to images of their own and a friend’s face distorted in opposite directions; the contingent aftereffects we observe are indicative of separate neural populations, but we suggest that these reflect coding of facial identity rather than of the categories “self” and “other.”

“…Using adaptation to distorted versions of the participant's own face, a famous face, or an unfamiliar face, smaller adaptation effects were observed when participants judged their own face than when they looked at other face types (Laurence & Hole, 2011). This finding suggests that greater experience/familiarity with specific faces may create a robust representation that is more difficult to alter via adaptation.…”

“…Adaptation effects have been shown to be smaller when judging one's own face rather than famous or unfamiliar faces (Laurence & Hole, 2011), suggesting that greater experience results in more robust representations that are less prone to adaptation. Our study provided an important opportunity to examine the influence of experience on adaptation effects using different classes of faces.…”

Face adaptation in an isolated population of African hunter-gatherers: Exposure influences perception of other-ethnicity faces more than own-ethnicity faces

Previous experiments have demonstrated that exposure to faces can change the perception of normality in new faces, such that faces similar to those at exposure appear more normal. Here we examined how experience influences adaptation effects in African Hadza hunter-gatherers, who have limited experience with White faces. We exposed participants to sets of either Hadza or White European faces that were manipulated to possess either wide-spaced or narrow-spaced eyes. We collected normality judgments both pre-exposure and post-exposure by showing pairs of images, one with wide-spaced and one with narrow-spaced eyes. Examining the difference between the preexposure and post-exposure judgments revealed that participants selected an increased number of images that were congruent with the faces to which they had been exposed. The change in normality judgments was strongest for White faces, suggesting that representations of White ethnicity faces are more malleable and less robust to adaptation, potentially because of the decreased experience that individuals had with them. A second experiment using the same test stimuli with a sample of White participants revealed equivalent adaptation effects for both Hadza and White faces. These data highlight the role of experience on the high-level visual adaptation of faces.

“…a very familiar face) had been used as the adaptor, a smaller aftereffect has been found relative to when the adaptor was a familiar or an unfamiliar face. Laurence and Hole (2011) have interpreted this result as indicating that the processing of the self-face requires a smaller amount of attentional resource and, thus, it produces a smaller level of 'neural fatigue' relative to other kinds of faces, which in turn may explain the reduced aftereffect. Further studies have shown no effect of familiarity on the magnitude of the aftereffect.…”

“…In order to manipulate familiarity, several studies have used images of famous people (Carbon & Ditye, 2011;Hills & Lewis, 2012;Walther et al, 2013), whereas in other studies participants had been trained with face stimuli (Jiang, Blanz, & O'Toole, 2007Ryu & Chaudhuri, 2006). Only a few studies have examined the effects of adaptation by using personally familiar faces (Rooney et al, 2012;Walton & Hills, 2012), or the participant's own face (Laurence & Hole, 2011;Rooney et al, 2012).…”

The Role of Familiarity on Viewpoint Adaptation for Self-Face and Other-Face Images

An adaptation method was used to investigate whether self-face processing is dissociable from general face processing. We explored the viewpoint aftereffect with face images having different degrees of familiarity (never-before-seen faces, recently familiarized faces, personally familiar faces, and the participant's own face). A face viewpoint aftereffect occurs after prolonged viewing of a face viewed from one side, with the result that the perceived viewing direction of a subsequently presented face image shown near the frontal view is biased in a direction which is the opposite of the adapting orientation. We found that (1) the magnitude of the viewpoint aftereffect depends on the level of familiarity of the adapting and test faces, (2) a cross-identity transfer of the viewpoint aftereffect is found between all categories of faces, but not between an unfamiliar adaptor face and the self-face test, and (3) learning affects the processing of the self-face in greater measure than any other category of faces. These results highlight the importance of familiarity on the face aftereffects, but they also suggest the possibility of separate representations for the self-face, on the one side, and for highly familiar faces, on the other.
